Thankyou guys for the quick reply,

some questions before I start to choose which one I will build:
1. where to buy that OT Transformer ? I can't find locally.
2. which one is better between two ? in term of sound quality, looks like the Kolibri is better ? why ? proven ?
3. any recommended speaker ? like 103dB ? I have 100 Coral speaker but not good at all. any better than Fostex ? beside Lowther ?
4. which one cost more between two ?

thank you again

The circuit design and transformers 53.43 (32 Euros each) are from Gerd Reinhoefer:

Peter Grundig has changed the input tube to the 5744 an designed a new case for the µVAC.
